Project description:This study aims at investigating the role of IL-17 in fluoxetine resistance in depression.The WGCNA analysis was utilized to analyze differentially expressed genes between response to antidepressant (GRA) group and resistance to antidepressant (AR)group. Furthermore, the treatment resistance model of depression was established inChronic unpredictable mild stress (CUMS) mice administrated with fluoxetine (widely used clinical medication for the treatment of depression) according to sucrose preference rate. Depression-like behaviors in mice were detected in Control group, CUMS group, GRA group, AR group, SR1001 (Th17 differentiation inhibitor) group. Subsequently, HT22 cells were exposed to IL-17 secreted by Th17 differentiation. Transcriptome sequencing from the Control and IL-17 group was used to screen differential genes. And then HT22 cells were transfected with si-JAK1 or si-STAT6. Th17 differentiation, the integrity of the blood-brain barrier (BBB), JAK1-STAT6 signaling pathway related proteins were detected by western blot, immunocytochemistry, flow cytometric analysis, ELISA experiments, immunofluorescence, and PCR. The inhibition of Th17 differentiation and the reduction of peripheral IL-17 release could increase their sensitivity to fluoxetine resistance and relieve the depression-like behavior. This process may be associated with the JAK1-STAT6 pathway.

Project description:STAT6 is a major transcription factor driving the polarization of Th2 cells in response to IL-4. STAT6 is phosphorylated by Jak1 and Jak3 kinases at the IL-4 receptor, after which phosphorylated STAT6 forms a homodimer and translocates into the nucleus. There STAT6 binds to specific DNA sequences, regulating the transcription of its target genes. Here we have analyzed on a genome wide level the STAT6 binding sites, after 1h and 4h of IL-4 induction, in naive human CD4+ T cells. Keywords: SRA Altogether 5 samples from 1 biological replicate were analyzed. Activated and IL-4 treated samples were compared to only activated or untreated samples to identify unique STAT6 binding sites after IL-4 induction.

Project description:Major depression is a multidimensional disorder highly prevalent in modern society. Although several classes of antidepressants (ADs) are currently available to treat depression, the effectiveness of treatment is still limited, as many patients do not show full remission; thus, there is a need to find better patients’ directed therapeutic strategies. Neuroplastic changes in several brain regions, namely in the hippocampal dentate gyrus (DG), are amongst the best correlates of depression and of ADs actions. In this study the targets and molecular mediators of chronic stress and of four ADs from different pharmacological classes (fluoxetine, imipramine, tianeptine and agomelatine) were investigated in the DG. Using the unpredictable chronic mild stress (uCMS) animal model of depression, the molecular commonalities and specificities of the ADs were determined. All ADs, except agomelatine, could reverse the behavioral deficits produced by uCMS, and the neuroplastic changes in the DG; agomelatine reversed only the anhedonic profile in the sucrose consumption test. Chronic stress induced mild but relevant molecular changes that were mostly reversed by fluoxetine, imipramine and tianeptine. Fluoxetine reduced pro-inflammatory response and increased cell metabolism pathways. Its actions were mostly dependent on molecular changes occurring in neurons. Similarities were found between imipramine and tianeptine molecular actions and targets, as both activated pathways related to cellular protection. Moreover, no particular neural cell type enrichment was found with both treatments. Agomelatine presented a very dissimilar molecular pattern impacting greatly on Rho-GTPases-related pathways in oligodendrocytes and neurons. The recognition of these molecular alterations contributes to the understanding of the processes implicated in the onset and treatment of depression and may pave the way for more effective therapeutic interventions. We compared gene expresssion in the dentate gyros of rats which were either untreated, exposed to unpredictable chronic mild stress, or exposed to the same stress and treated with either fluoxetine, imipramine, tianeptine, or agomelatine

Project description:Lactation causes dramatic maternal calcemic adaptations where up to 10% of maternal bone density is mobilized for milk calcium. Serotonin plays a role in regulating this calcemic demand through alterations in DNA methylation. Selective serotonin reuptake inhibitors used to treat peripartum depression exacerbate this signaling. The first objective of this study was to determine the impact of fluoxetine, one of the most popular selective serotonin reuptake inhibitors, on the transcriptome of the mouse mammary gland during peak lactation. The second objective was to determine whether supplementation with folic acid, a well-known methyl donor, would mitigate the gene expression changes induced by fluoxetine.

Our aim was to examine a subcellular compartment enriched in proteins involved in synaptic function.

Project description:Selective serotonin reuptake inhibitors (SSRIs) such as fluoxetine are the most common treatment for major depression. However, approximately 50% of depressed patients fail to achieve an effective treatment response. Understanding how gene expression systems relate to treatment responses may be critical for understanding antidepressant resistance. Transcriptome profiling allows for the simultaneous measurement of expression levels for thousands of genes and the opportunity to utilize this information to determine mechanisms underlying antidepressant treatment responses. However, the best way to relate this immense amount of information to treatment resistance remains unclear. We take a novel approach to this question by examining dentate gyrus transcriptomes from the perspective of a stereotyped fluoxetine-induced gene expression program. Expression programs usually represent stereotyped changes in expression levels that occur as cells transition phenotypes. Fluoxetine will shift transcriptomes so they lie somewhere between a baseline state and a full-response at the end of the program. The position along this fluoxetine-induced gene expression program (program status) was measured using principal components analysis (PCA). The same expression program was initiated in treatment-responsive and resistant mice but treatment response was associated with further progression along the fluoxetine-induced gene expression program. The study of treatment-related differences in gene expression program status represents a novel way to conceptualize differences in treatment responses at a transcriptome level. Understanding how antidepressant-induced gene expression program progression is modulated represents an important area for future research and could guide efforts to develop novel augmentation strategies for antidepressant treatment resistant individuals. 38 samples, 2 dentate regions (dorsal/ventral), 3 groups (control, antidepressant resistant (4 mice), antidepressant responsive (7 mice), untreated (8 mice).

Project description:Aberrant signal transduction contributes substantially to leukemogenesis. The Janus kinase 1 (JAK1) gene encodes a cytoplasmic tyrosine kinase that noncovalently associates with a variety of cytokine receptors and plays a nonredundant role in lymphoid cell precursor proliferation, survival, and differentiation. Somatic mutations in JAK1 occur in individuals with acute lymphoblastic leukemia (ALL). JAK1 mutations were more prevalent among adult subjects with the T cell precursor ALL, where they accounted for 18% of cases, and were associated with advanced age at diagnosis, poor response to therapy, and overall prognosis; We used microarray to compare the gene expression profile of JAK1 mutation positive or negative ALL blasts Experiment Overall Design: Thawed or freshly isolated T-ALL cells (>90% blasts) were homogenized, total RNA was extracted and hybridized on Affymetrix microarrays
